IMPROVEMENT IN COMBINED THRESHER, SEPARATOR, AND CLOVER-HULLER.

The Schedule referred to in these Letters Patent and making part of the same.

To all whom it may concern Be it known that I, ADRIAN CORNELL, of Newtown, in the county of Bucks, and State of Pennsylvania,

.have inventedcertain new and useful Improvements description.

The object of my invention is to combine mechanism for hulling clover-seed, and for separating, cleaning, and bagging grain, in one machine, and thus save the expense of two separate machines; to which end,

The improvements herein claimed consist First, in a novel method of combining a threshing cylinder and longitudinally-reciprocating screens, with a hulling-cylinder, located between the upper screens and lower shaking-shoe, and with a fan.

Second, in a novel method of combining a hullingcylinder, located between the upper and lower screens, with a reversible or movable cant-board, which, in one position, forces the seed to pass through the boilingapparatus, and in another acts as a deflector, to convey the grain directly to the lower screen.

Third, in a novel method of mounting the shakingscreens on adjustable radius-bars, as hereinafter described. 7

Fourth, in a novel method of combining, with the separator, a device for elevating and bagging the grain, as hereinafter described.

The accompanying drawings represent all my improvements embodied in a machine, similar in some respects to that patented by me, May 21, 1867. V

Figure 1 is a view, in elevation, of the left side of the machine.

Figure 2, a similar view of the right sideof the same.

Figure 3, a plan or top View of the same.

Figure 4, a rertica-l longitudinal section, through the same, at the line :0 :t of fig. 1.

For convenience of reference, I designate that end of the machine at which the grain is fed in as the front, and that at which it is discharged, as the rear.

I also call that side of the machine which is on the right-hand side of a person standing at and facing the front of the machine, the right side, and the opposite, the left side.

The mechanism is mounted in a stout frame, A, of suitable construction, and driven by power applied to a connter-shaft, B, from any suitable prime mover, in any proper well-known way.

This shaft B is arranged transversely on the front of the frame, beneath the table G, in front of which the operator stands on a suitable platform, not shown in the drawings A tln'eshing-cylinder, D, to be provided with a concave, of the usual construction, is mounted on a shaft, ti.

Two parallel shaking-screens, E, have a compound longitudinal reciprocating and rising and falling movement imparted to them by cranks, on a shaft, E, as described in my patent aforesaid.

The screens vibrate parallelly to each other, but in opposite directions, and are separated by a stationary centre-bar, 0.

Their front ends have each one bearing only on the crank, to reduce the friction, while their rear ends vibrate on bifurcated radius-bars e, pivoted in eye bolts 0*, which can be screwed up or down, to vary the inclination of the shaker.

A hulling-cylinder, E, is mounted'on a shaft, f, and provided with a suitable concave. This cylinder is only used when hulling grass-seed.

In order to adapt the machine to cleaning grain, the cant-board f of the huller. is turned on its axis, so as to cover the opening, f over the cylinder, so as to convey the grain direct-l y to thelower screens g, in a shaking-shoe, G, suspended in the frame by radiusbars g, and vibrated longitudinally by a ,pitman, h, from a crank on the fan-shaft It, carrying a fan, H, of the usual construction.

In order to regulate the force of the blast, an escapevalve, I, on the fan-case, is mounted on a rock-shaft, i, carrying at each end a throttle-valve, l, which works over the lower part of the air-opening of the fan.

Each end of the rock-shaft t is concave, and fits on a pointed steel bearing in the brackets t, thus allowing it to rock with but little friction.

A counterbalance, 13 shown in fig. 4, working on a screwed spindle, regulates the pressure at which the escape-valve opens, and the throttle-valves close.

, An elevator, J, on the left-hand sidepf the machine, returns the tailings to the cylinder, to be rethreshed, while a corresponding one, K, on the opposite side, elevates the cleaned grain or seed into a hopper, It, provided wit-h a slide-valve, it, through which it drops into bags suspended by books I, from aring, L, adjustable, up or down, in slots in the post 1', to suit bags of different sizes.

A spout, 7., shown in red lines in fig. 3, conveys the cleaned grain from the hopper to the elevator 7c.

The operation is as follows:

In threshing clover-seed, the clover is fed by the attendant into the tlneshi'ng-cylinder D, from the table 0. The clover passes from the cylinder D to the screens E, the seed falling through the screens, while the stalks pass 05 at the back, as usual. The seed then passes between the hulling-cylinder and its concave, as shown-by the blue arrows, fig. 4, and thence falls upon the screen y, where it is thoroughly winnowed, the chaff being blown out by the blast.

The tailings may be returned to the cylinder D, to be rethreshed by the usual spouts J, shown in red lines in 3, connecting the conveyor and the receptacle, into which they fall. 7

The clean seed may be in like manner elevated into the hopper, and discharged into bags.

In cleaning grain,-the operation is the same, except from the screens E to the lower screen that the cant-board, f, is reversed over tliecylinder, as shown in red in fig. 4, to conduct the grain directly g, without passing through the huiling-apparatus.

In cleaning seed, a band, m, from the power, passes over the pulley M, on the counter-shaft B, and encircles a pulley, F, on the hulling-cylinder F. A band, it, encircles a pulley, N, on the opposite end of the shaft j, and a pulley, D, on the threshing-cylinder, which it drives. The fan is driven by a band passing from a pulley, O, on the counter-shaft, around a pulley, H, on the fan-shaft.

A band, from a pulley, P, on the counter-shaft, drives a pulley on the elevator K.

A similar band, from a pulley, R, on the countershaft, drives a pulley, R, on the shaft which vibrates the screens E.

A band, 8, from a pulley, S, on the opposite end of this shaft, drives a pulley on the tailings-elevator.

In cleaning grain, the band m is removed from the milling-cylinder F, and encircles the threshing-cylinder pulley, and the cantboard reversed, as before described. v

The red arrows, in the drawings, indicate the direction of the movements of the various parts; the blue arrows, the directions of the grain; and the yellow arrows, that of the blast.

' What I claim as my invention, and desire to secure by Letters Patent, is-

1. The combination of the threshing-cylinder D, screens E, hulling-cylinder F, fan H, and shakingshoe G, the combination being and operating substantially as set forth.

2, The combination, with the hulling-cylinder D and screens E, of the reversible cant-board f, substantially as set forth.

3. The combination, with the screens E, of the radius-bars e and adjustable eye-bolts e, as and for the purpose described.

4. The combination, with the elevator K, of the vertically-slotted post, and adjustable bag-holder L, constructed and operating substantially as set forth.

In testimony whereof, .I have hereunto subscribed my name.
